Electronic cigarette

ABSTRACT

An electronic cigarette including an atomization assembly and a battery assembly. The battery assembly comprises an overtime work protection unit. The overtime work protection unit comprises a control panel; when the electronic cigarette works continuously for over a preset time limit in a single puffing period, the overtime work protection unit automatically shuts off a power supply to the control panel.

BACKGROUND

The disclosure relates to an electronic cigarette.

Known electronic cigarettes have no overtime work protection function.

SUMMARY

The disclosure provides an electronic cigarette comprising anatomization assembly and a battery assembly. The battery assemblycomprises an overtime work protection unit. The overtime work protectionunit comprises a control panel; when the electronic cigarette workscontinuously for over a preset time limit in a single puffing period,the overtime work protection unit automatically shuts off a power supplyto the control panel.

The set time limit is 10 seconds.

The overtime work protection unit further comprises a spring contact anda battery; an output end of the battery is connected to an input end ofthe control panel; an output end of the control panel is connected tothe spring contact to supply power for the atomization assembly; thespring contact is connected to an input end of the atomization assembly;the control panel comprises a pneumatic switch activatable by vapor totrigger the control panel to output a voltage to the atomizationassembly; when a continuous activation time of the pneumatic switchexceeds 10 seconds, the overtime work protection unit automaticallyshuts off the power supply to the control panel.

When the overtime work protection unit is driven to touch theatomization assembly, a closed loop circuit is formed thereby lightingup an LED light disposed on the control panel.

The atomization assembly is disposed on the battery assembly; theatomization assembly comprises a magnet and the battery assemblycomprises a stainless iron adsorbing on the magnet.

The battery assembly comprises the overtime work protection unit. Whenthe electronic cigarette works continuously for over 10 second in onepuffing period, the overtime work protection unit automatically shutsoff the power supply to the control panel, thus preventing theatomization assembly from being burned out. The overtime work protectionunit further comprises a power indicator. When the atomization assemblyis electrified, the LED light disposed on the control board will belighted up thereby indicating that the atomization assembly has beenpowered on and starts to work.

DETAILED DESCRIPTION

To further illustrate, embodiments detailing an electronic cigarette aredescribed below. It should be noted that the following embodiments areintended to describe and not to limit the disclosure.

As shown in FIGS. 1-5, an electronic cigarette comprises an atomizationassembly A and a battery assembly B. The atomization assembly A isdisposed on the battery assembly B.

The atomization assembly A comprises an e-liquid tank 1, a first sealring 2, a limit cover 3, a second seal ring 4, a ceramic core 5, a thirdseal ring 6, a seal gasket 7, a base 8, a silica pad 9, a joint 10, aseal plug 11, an iron shell 12. The first seal ring 2 is disposed on thetop of the limit cover 3. The second seal ring 4 is disposed on theceramic core 5. The third seal ring 6 is disposed on the bottom of theceramic core 5. The second seal ring 4, the ceramic core 5, and thethird seal ring 6 are disposed in the limit cover 3. The seal gasket 7is wrapped around the base 8. The limit cover 3 is disposed on the sealgasket 7. The silica pad 9 is inserted in the base 8. The joint 10 isinserted in the silica pad 9. The seal plug 11 is disposed on the bottomof the base 8. The base 8 is disposed in the e-liquid tank 1, and theiron shell 12 is wrapped around the base 8.

The battery assembly B comprises a spring contact 13, a magnet 14, asupport frame 15, a lampshell 16, a cap 17, a button 18, a battery 19, asilica ring 20, a silica gasket 21, a control panel 22, a bolt 23, and ahousing 24. The spring contact 13 and the magnet 14 are disposed on thetop of the support frame 15 for electric conduction and connection tothe atomization assembly. The battery 19 comprises an output endconnected to an input end of the control panel 22 to supply power to thecontrol panel 22. The silica ring 20 is disposed on a pneumatic switchon the control panel 22. The silica gasket 21 is disposed on a powerbutton of the control panel 22 to protect the power button and exhibitsinsulation function. The cap 17 is disposed on the silica gasket 21 toensure the stress balance when the power button is pressed. The button18 is disposed on the cap 17. The control panel 22 is disposed in thesupport frame 15 and is fixed by the bolt 23. The support frame 15 isdisposed in the housing 24. The lampshell 16 passes through the openingsof the housing 24 and the support frame 15 and is fixed on an LED lightelement on the control panel 22, to gather and transmit the light out ofthe battery.

The battery assembly comprises an overtime work protection unit. Theovertime work protection unit comprises a control panel; when theelectronic cigarette works continuously for over a preset time limit ina single puffing period, the overtime work protection unit automaticallyshuts off a power supply to the control panel. Optionally, the set timelimit is 10 seconds.

It will be obvious to those skilled in the art that changes andmodifications may be made, and therefore, the aim in the appended claimsis to cover all such changes and modifications.
